Facility location coordinates

I was able to decipher the hex coordinate system, and have used that to draw a map using the individual hexes, making up territories, which make up the continent. However, each facility also has an additional set of coordinates that I can't seem to figure out.

There is a set of "location_x", "location_y", and "location_z", but there's no indication of what those represent. I'm assuming that they give the coordinates for the "center" of the territory (that is used on the in-game map as a circle with a facility type icon inside), but I can't seem to make heads or tails of them.

For example:
http://census.daybreakgames.com/get/ps2:v2/zo...t:1^inject_at:hex^hide:zone_id'map_region_id)

• "facility_id": "120000",
• "facility_name": "Indar Western Warpgate",
• "facility_type": "Warpgate",
• "facility_type_id": "7",
• "location_x": "-2275.0",
• "location_y": "480.0",
• "location_z": "-2490.0",
• "map_region_id": "2202",
• "reward_amount": "10",
• "reward_currency_id": "2"

I'm also assuming that these coordinates are also related to the "hex_size" value for the continent (200 in this case for Indar), but they don't seem to be standard x,y coordinates for the overall map as I would have expected.

Any help would be greatly appreciated

 

After spending some time playing with the coordinates of the major facilities on Indar in varying combinations, I think I have figured out what these mean:

"location_z" is the x-coordinate
"location_x" is the y-coordinate
and presumably "location_y" is the vertical altitude
